Now that I look at the code in the light of day, it is even simpler than
that! Try this.

;----------------------------------------------------------- --
img1 = cgDemoData(7)
img2 = congrid(img1, 360, 180)
cgDisplay, 900, 450

pos = cgLayout([2,1], OYMargin=[4, 11], OXMargin=[5, 8], XGap=6)
pos1 = pos[*,0]
img1pos = cgAspect(Position=pos1, Aspect=img1, Align='top')
cgImage, img1, CTIndex=3, /AXES, POSITION=img1pos, OPOSITION=op
cgColorbar, CTIndex=3, /Fit

pos2 = pos[*,1]
img2pos = cgAspect(Position=pos2, Aspect=img2, Align='top')
cgImage, img2, /AXES, POSITION=img2pos, CTIndex=2, /NoErase
cgColorbar, CTIndex=2, /Fit
END
;----------------------------------------------------------- --
